Abstract:
|
As there is an extensive body of research on diagnostics in regression models, various outlier detection methods have been developed. These methods have been extended to mixed effects models and generalized linear models, but there exist intrinsic drawbacks and limitations. This paper presents two-dimensional plots to identify discordant subjects and observations in generalized linear mixed effects models, displaying discordance in two directions. The TRSS is not an extension of any regression tools but a new approach designed to efficiently reflect the characteristics of repeated measures. Applications to real-life examples are presented to illustrate the favorable/beneficial performance of the new tool.
